Remapping a diesel engine gets you a more power, more economy it sounds too good to be true.
Many people often talk about their latest mods and power figures. Many of them go ahead and remapped their vehicle’s diesel engines and boast of more power, better economy and unchanged reliability.
Diesels have actually come so far in an actual short time. Back in the 1980’s they were related with being noisy, smelly and smoky. Now the Turbo diesel engine is a advanced beast and offers massive amounts of torque. We are seeing our associates swayed away from petrol due to the huge amounts of torque on offer from a well-tuned diesel engine. As engine technology has better-quality, the diesel revolution has begun. As soon as manufacturers started adding turbos to their engines we started to see huge power figures.
To further rub salt into the Petrol owners wounds the legendary diesel fuel economy has remained or in many cases improves after a remap. More BHP, oodles of Torque and better MPG. It almost seems to be too good to be true. The average power gains from a remap on a diesel engine are in the order of 30% more power. The costs vary from provider to provider.
OBD tuning offers you an easy way to change the calibration and supplies the necessary tools to arrive at an optimum calibration, this way it is possible to make supreme use of the modifications done to your engine. An appropriately calibrated ECU will result in more power, better mileage, cleaner exhaust emissions, better throttle response and more reliability. It is also possible to modify things like fan kick in temperature, throttle speed, rpm limit etcetera. A build in power measurement option is also available so you can exactly see how much and where power is gained with a modification or calibration.
Car ECU (engine control unit) flash re-programmable PCMs have been in vehicles for over a decade. The first such application was the 1990 Geo Storm.
Why a routine car like the Storm would be the first to receive a flash re-programmable computer system is unknown. You would think GM would have chosen a more high profile car like a Cadillac or Corvette to usher in the new technology. But they didn’t.
